Insects Are in Serious Trouble

Years ago when I lived in suburban Texas with a typical suburban house with a back yard that had open space behind it I had a terrible insect problem. Exposed skin would get a mosquito bite-per-minute, the dogs were coming inside covered in fleas, etc. So I went to Home Depot and bought this yard spray that promised to kill mosquitos, fleas, ticks, etc. and I hosed down the back yard in a desperate attempt to reclaim it for our families use.<p>What struck me as soon as I was done spraying the yard was how quiet it was. It was eerie. It then occurred to me that I hadn&#x27;t just killed the pests, I had killed <i>everything</i>.<p>These sorts of products are in every hardware store. How many other people just casually eliminate all insects in their yard, and perhaps do so frequently? What do those chemicals do when they wash away into the watershed? Same question for all the chemicals used in agriculture - it can&#x27;t be good, right?<p>In a way it boggles the mind that this is an acceptable product, which is socially acceptable to use. I certainly regret it, but I seem to be in the minority.

I think nothing will change as long as <i>economic growth</i> is understood as <i>economic Good</i>.<p>Current economy can&#x27;t work if there&#x27;s no economic growth.<p>Banks are among the biggest culprits. If banks lend money at a 5% interest rate, their customers must grow their businesses by 5%.<p>A new, sustainable economy is needed. I think about it each time I see the Race for the Galaxy card. I&#x27;ve seen a radical example of this among African tribes, in a documentary Africa serries by Basil Davidson. He argued the tribe (sorry I don&#x27;t remember its name) can fully sustain itself by taking things from nature around it. All their wealth is external. They possess little, but whenever they have a need for something - food, medicine, water, paint, clothes, containers(...) they go to a forest, harvest a specific plant and get it. They have recipes for everything they need.

It saddens and frustrates me to no end that this is the kind of work that the EPA should be doing for the long term good of our country and species and knowing that it is being systematically dismantled from the inside (as many of our federal agencies are). We&#x27;ve given the keys of the hen-house to the foxes and are sitting back to watch our manufacturing jobs roll in. Granted this problem was already occurring and economics almost always takes precedence over the environment <i>overall</i>, but the fact we&#x27;re going backwards makes me furious.<p>Scott Pruitt Is Carrying Out His E.P.A.

I believe the primary source was discussed last week.

As sad as this is, the reality is that nobody cares. Biologists have been beating the conservation drum (rightly so) for decades but the behaviour of the average consumer has hardly changed. Arguably, it&#x27;s actually gotten worse with metrics like the use of plastic at an all-time high [1] (thanks, bottled water). Soon enough we will learn what the economic value of the free labor provided by insects and other animals as basic agricultural processes like pollination become a service that must be paid for (on many farms this is actually already the case).<p>The good thing about capitalism is that it&#x27;s great at optimizing a cost&#x2F;value equilibrium for things that are easy to quantify. But the bad thing about capitalism is that things that are hard (or impossible) to quantify are, at best, an afterthought. Resulting in the all-too-familiar tragedy of the commons.<p>[1] <a href="https:&#x2F;&#x2F;www.plasticsinsight.com&#x2F;global-consumption-plastic-materials-region-1980-2015&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.plasticsinsight.com&#x2F;global-consumption-plastic-m...</a>

Just some wishful thinking here...<p>Is it possible that the local insect populations got wise to these malaise traps that the researchers were using in western germany?<p>Apparently the way that a malaise trap works is that it waits for insects to fly into it&#x27;s wall, hopes that they crawl up the wall, and then hopes that they crawl right into a bottle filled with ethanol.<p>Now I do not know anything at all about insects and how they might learn or adapt to various situations.<p>But I know that they can adapt just like anything else, and maybe some of them starting saying &quot;no I will not crawl up that screen into the bottle of alcohol&quot; after 27 years and got the word out to other local insects?<p>Am I crazy for thinking that might be the case?

I&#x27;m glad to see some of the recent research on threats to insect populations getting more attention, HN recently had a good discussion on this in &quot;75% decline over 27 years in total flying insect biomass in protected areas&quot; [1]. But in reading through that thread I saw a lot of discussion about pesticides but surprisingly nothing at all regarding nighttime light pollution, and in that context I think another Atlantic piece is of interest, &quot;Night Lights Drive Pollinators Away from Plants&quot; [2]. In particular I think that&#x27;s an area where it seems like there is more direct action potential for technologists. Both individually and in terms of community ordinances we should push to better take advantage of advances in LEDs and sensors to try to reduce color temperature at light and try to better ensure that lighting exists only when and where humans actually directly need it at the time, rather then the current dumblight defaults of &quot;always on, lots of spread, and always at the same temperature&quot;.<p>This should be an area where at least some level of technological win-win is possible, because we generally only need lighting on when a human is not present. Permanent-on has just been that way by default because there was no better way to ensure it would be on if somebody came around. Fixed color temperatures too have been a matter of simple necessity given the technology available. So there should be a lot of room to reduce wasted light (and in turn energy) and simultaneously benefit pollinators via smarter lighting tech.<p>From a personal perspective, this provided me the impetus to get my camera, door sensors, and other presence detectors all linked up with my lighting at long last so that my outdoor lighting is by default off at night except when directly needed. I&#x27;d support a national push to develop more directed, warmer, and smarter street lighting and the like as well.<p>----<p>1: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=15502074" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=15502074</a><p>2: <a href="https:&#x2F;&#x2F;www.theatlantic.com&#x2F;science&#x2F;archive&#x2F;2017&#x2F;08&#x2F;confirmed-night-lights-drive-pollinators-away-from-plants&#x2F;535983&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.theatlantic.com&#x2F;science&#x2F;archive&#x2F;2017&#x2F;08&#x2F;confirme...</a>

I wonder what this comment section would like if this study was released during last year&#x27;s Zika panic.

I wonder if sunlight &#x2F; cloud cover negatively affects insect population.

we really need to band all insecticides, pesticides, and herbicides.
